Yes. Mostly smooth.
I had 1 scenario where the guy "deposited" the money, sent an uber to collect and I received an SMS from my bank.
When I checked my account online, it showed the money deposited, but not available. It was never going to be available, as they deposited a cheque at an atm in potch, which would have bounced.
Luckily i dodged that one. The uber driver was not aware of the scam, he simply got a fare and accepted it.
Listed a phone on Gumtree once, won't do it again. Was constantly messaged by people with all kinds of silly offers but none that ever materialised into anything. Ended up just selling it on Bidorbuy which is a lot less hassle.
